Abstract:

This study is focused on the feasibility that utilized the sealed spectrophotometer to measure the COD_Cr of bleaching effluent. The results of t-test demonstrates that it can be used for the measurement of COD_Cr the same as the method described in standard method,and the Pearson coefficient is 0.999 5.

Key words: spectrophotometer, bleaching effluent, sealed tube method, COD
